Application filed February 15, 1915. Serial No. 8,399.

To all whom it may concern: Y Be it known that I, CARL 7WOLF, manufacturer, a citizen of Germany, residingv at Schweinsburg on the Pleisse, Germany, have invented certain new and useful Improvements inFurnacesfor Heat-ing Vtater and Generating Steam, of which the following is a full, clear, and. exact description, reference being had to the accompanying drawings, forming part of this specification.

The invention relates to that class of fur-v naces which are provided with .several Vertr- .can enter into each of the flues with the result that the gases of the several fuel chambers are mixed together, so that aperfect combustion is obtained. A.

In the accompanying drawings Figure 1 is a vertical longitudinal section through the furnace on line B-B of Fig. 2. Fig. 2 is a horizontal section on line AA* of Fig. 1. Fig. 3 is a vertical cross section on line D--D of Fig. 2. Fig. 4 is a horizontal section on line C-C of Fig. 1.

On the base S of the furnace are arranged the vertical water chambers 1, 2, 3, 4, 5, 6, 7, 8, 9 and 10, inclosing the fuel chambers B1 B2 B2. The water chambers are fed with water by the main pipe H through the branches t, t2 t3 t2 and t5. The branch t, is connected with the water chambers 1, L and 8, and the branch t, with the chambers 3, 7 and 10. rl`he branches 2 and t4 are connected with the inner water chambers 5 and 6 respectively, and the branch t3 is connected with the chamber 2. By the pipe Ir, the chambers 8 and 9 are connected and by the pipe r2 the chambers 9 and 10, so that all chambers are connected with each other. The front chambers 8, 9 and 10 are provided in the upper part with openings 11, through which the fuel can be fed to the chambers B1 B2 B3. All water-chambers are connected with an upper common receiver l2.

\ The water-chambers 4 and 7 are connected 16 and 17and the water chambersrS, 5, 9, 6

and 10 are connected with thesaid receiver' bythe pipes 18, 1 9, 20,221 and 2,2. The receiver consists of several boxes 12, 112 212, arranged one above the other and connected bysuitable pipes or passages. n 2

'Ihe common combustion chamber E,ar rangedabove the fuel chambers B1 B2 B3 is connected with two flues, beginning at opposite ends of the combustion'chamber, one being arranged in the front part of the furnace, the other on the back part. These flues extend in opposite directions and are separated from each other by a vertical ipar tition. furnace is shown in, Fig. 1. It begins with the rising channel R1 which is connected at its lower end with the. common combustion chamber E through the opening O1. Thek upper end of this channel leads to the channel R2 running fromtheleft to the `right hand above the box 212. This channel leads to the channel R3 runningin the opposite direction between the boxes 212 and 112, and R3 leads to the channel R4 running from theleft to the right hand between the boxes 112 and 12 and terminating in the downward deliverey channel Z2.

The iiue of the back part of the furnace, running in the opposite direction begins with the channel L1, on the right side of Fig. e, which is connected at its lower end with the common combustion chamber E through the opening O2. The upper end of this channel leads to the horizontal channels L2 L3 L4, shown on the left side of Fig. 3, terminating in the downward delivery channel Z1. The downward delivery channels ZI and Z2 are of the breadth of the furnace. The front part of the delivery channel Zl is separated from the rising channel It, arranged in the upper part of the furnace, by a horizontal partition s, (Fig. 1). In the same manner the back part of the delivery channel Z2 is separated from the rising channel L, by a horizontal partition.

The pipes t, and t5 are connected with the upper boX of the receiver by groups of heat ing pipes o, and o2, arranged in the delivery channels Z1 and Z2 respectively. The boX 212 is provided with two connection pipes The Hue of the front'part of thel F1 and F2 from which hot water may be drawn off or these pipes may be connected with a steam receiver.

The working of the furnace is as follows: If all water chambers 1 to 10 are filled with water, the fuel chambers B1 B2V B3 are filled through the openings 1l with briquets, which are ignited from the top, so that they burn downward. The ire gases, produced in the fuel chambers are miXed in the upper combustion chamber E and pass to the Hue R1 or Ll or to both of them. If the combustion is slower' in one of the fuel chambers than in another one, the gases, produced by this slow combustion, will follow in the combustion chamber E the gases produced by the other chambers and become mixed with the same and burn without any addition of fresh air. v

As there are several fuel chambers, independent one of the other, the furnace can be used with one or two chambers remaining unfilled. 'The ignition of the fuel, when the furnace is used, is effected in such a manner, that an empty fuel chamber is filled with briquets to such a height, that the briquets enterin the common combustion chamber E. The fire gases, produced in the other fuel chambers will then ignite these briquets, so that a special implement for igniting the briquets is not necessary.

Having fully described my invention, what I claim, and desire to secure by Letters Patent is- 1. A furnace comprising a plurality of vertical water chambers connected with each other and arranged to form independent fuel chambers, a combustion chamber common to Copies of this patent may be obtained for theV latter, flues extending from opposite sides of the combustion chamber, one of said lues being arranged in the front and the other in the back part of the furnace and constructed to cause the fire .gases in the front and back flues to move in opposite di rections. Y

2. A furnace comprising a plurality of vertical water chambers connected with each other and arranged to form independent fuel chambers, a combustion chamber common to the latter, and two flues separated from each other, each flue having a rising channel on one side of the furnace and a downward de livery channel on the other side of the furnace and one or more horizontal channels between the rising and the delivering channels.

3. A furnace comprising a plurality of vertical water chambers connected with each other and arranged to formindependent fuel chambers, a combustion chamber common to the latter, two flues arranged in the upper CARL WOLF.
